Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18604, here are decompositions:
- 11 + 18593 = 18604
- 17 + 18587 = 18604
- 83 + 18521 = 18604
- 101 + 18503 = 18604
- 191 + 18413 = 18604
- 233 + 18371 = 18604
- 251 + 18353 = 18604
- 263 + 18341 = 18604
Showing the first eight; more decompositions exist.
